Soil and water conservation in a small agricultural catchment

Original language description

Intensive farming in the Czech Republic brings nutrients and also a manifold spectrum of pesticides into the arable land. Research on nutrients and pesticides in soil, sediment and surface water has been proceeding in experimental catchment Němčice stream since 2019. It represents typical highland conditions in the CR, with slopy relief and intensive farming on large blocks. The total nitrogen, total phosphorus and pesticide concentrations in soils were monitored in transects covering the basic slope zones of each catchment. Samples of bottom sediments were taken from the stream and the reservoir. The surface water samples were taken at gauging profile in the stream (enabling monitoring of hydrological characteristics) and from the reservoirs every month during vegetation season. Obtained results showed a need to pay close attention to all potential contaminants in the environment, considering the transport processes in agricultural catchments and potential mutual influences on various environment components. Limiting the entry of potentially risky substances (nutrients and pesticides) from agricultural land into the aquatic ecosystem is theoretically possible by reducing application doses or slowing down transport processes. The second option is the principle of the presented comprehensive soil and water conservation measures. The effect of complex measures consists in mitigating the effects of surface soil washing by water erosion, slowing down leaching of substances through the soil profile, improving the quality of subsurface water. The measures (change in the sowing procedure, belt distribution of crops, grass belts, hedges, ditches, …) are multifunctional in nature, which means that in addition to limiting soil degradation and contamination of surface water bodies, they contribute to increasing water retention in the agricultural landscape, mitigating the manifestations of hydrological extremes (torrential rainfall and drought) and have the potential to have a positive effect on the ecological stability and aesthetics of the agricultural landscape. They can be implemented by farmers or in process of land consolidation.
